Features and benefits of your new Quattro-SL pedestal
The Quattro-SL pedestal has been specifically designed to meet the exacting demands of camera
operators working with full facility studio cameras. The Quattro-SL pedestal offers many unique
features to assist in framing and accurate and repeatable shot positioning.
• Suitable for a wide range of payloads up to 80 kg (176 lb).
• Narrow base and small footprint allow you to manoeuvre into smaller areas, tight sets
and standard 30-inch doorways.
• Low-friction wheels reduce the steering effort, providing a sensitive feel.
• On-shot stroke of 100 cm (39.4 in.) and a maximum height of 147 cm (58.3 in.) provides
increased creative angles and means that raised platforms are not needed to obtain
eyeline.
• Balance profile reduces effort across the full height range, reducing the effort needed
to raise the column.
• The adjustable skirt is protected by the base, reducing damage and improving relia-
bility and allowing close floor clearances for small-diameter cables.
• The foot-operated brake allows the pedestal to be parked safely and securely.
Once again, thank you for choosing the Quattro-SL
We are confident it will give you many years of reliable
performance

Introduction
The Quattro-SL pedestal comprises a central four-stage telescopic column mounted in a steerable
base.
The moving column (5) is pressurized from an external pressure source. A markable height indi-
cator scale is provided on the second section of the column allowing the operator to record camera
heights for shots. A weight tray (2) is attached to the top of the column and trim weights (1, 19)
are provided for fine balance. The weight tray also provides a standard four-bolt mounting (20) for
a pan and tilt head and the pedestal is steered by means of a steering ring (4) mounted on its un-
derside. Large- and small-diameter steering rings are available and are fitted with indicators (21)
to show the straight-ahead position.
The column is locked in the fully-depressed position by two safety catches (3) on the weight tray
which engage with spigots (18) at the base of the column. An on-shot clamp (6) and a drag control
(17) are provided at the base of the column.
The base is carried on three sets of twin 125 mm (5 in.) wheels. A continuous height-adjustable
cable guard with infinite positions is provided, raised and lowered by a single control knob (10)
with a height indicator (11) below. Stowage for the trim weights is provided on the upper surface
of the base (8) and two cable clamps (13) are fitted to the vertical sides. A brake pedal (14) con-
trols the parking brake and a crab/steer pedal (15) allows the operator to switch between conven-
tional and crab steering. Position indicators (12) on each side of the base allow the camera
operator to accurately position the pedestal. Lifting apertures (9) are provided on each face of the
base and these also provide access to the wheels.

Fitting the load
The Quattro pedestal has the standard four-bolt mounting plate (20) which permits the use of var-
ious Vinten camera mounts including pan and tilt heads, Quickfix and Mitchell adapters. To fit a
pan and tilt head or an adaptor it is necessary to extend the moving column.
Fit the pan and tilt head or adaptor as follows:
Ensure pedestal pressure does not exceed 3.5 bar (50 psi). Reduce as necessary, using
the Schrader valve cap (16).
Push down on the weight tray (1) against residual pressure. At the safety catches (3), push
the rocker switches to the unlocked position. Allow the column to extend under hand re-
straint.
Apply the on-shot clamp (6).
Fit the pan and tilt head or adaptor and secure with the appropriate bolts.
Release the on-shot clamp (6) and lower the moving column under hand restraint. Push
down on the weight tray (1) and push the safety catch rocker switches to the locked posi-
tion.
With the pedestal locked in the fully depressed position, fit the camera and accessories to
the pan and tilt head, ensuring that all items such as pan bars, prompters, lenses etc, are
fitted. Attaching these items at a later stage may upset the pedestal balance.
Install one main (19) and two auxiliary trim weights (2) on the weight tray (1).
WARNING! A pressurized pedestal will rise rapidly when the safety catches
are released. Do not lean over the pedestal when releasing the
safety catches. Always restrain the column by hand pressure
on the weight tray when the safety catches are released.
WARNING! A pressure retaining valve prevents pedestal pressure being
reduced below approximately 3.5 bar (50 psi), indicated by the
yellow segment on the pressure gauge (7).
In the event that pressure has fallen below this, pressurize the
pedestal to approximately 3.5 bar (50 psi) before attempting to
extend the column.
WARNING! Lock the pedestal in the fully depressed position before install-
ing the camera.

Pressurizing the pedestal
The Quattro may be pressurized from an external pressure source or by using the Vinten portable
pump (Part No. 3357-3). Trim weights (2), (19) are provided for fine balance.
Ascertain the payload to be fitted to the pedestal (payload = pan and tilt head, camera, lens and
all ancillary equipment). Referring to the Pressurization graph, mark the payload on the horizontal
axis then strike a vertical line from the load figure to the balance line. At the intersecting point strike
a horizontal line to the vertical axis and read off the required pressure.
The pedestal should be pressurized with the column unlocked and free to extend.

Pressurizing the pedestal from an external pressure source
To pressurize the pedestal from an external pressure source, proceed as follows:
Remove the Schrader valve cap (16) and connect the charging line from the pressure
source.
Push down on the weight tray (1) against residual pressure. At the safety catches (3), push
the rocker switches to the unlocked position.
Turn on the pressure supply and slowly increase the pedestal pressure to the required pres-
sure. Do not exceed the maximum working pressure, indicated by the leading edge of the
red sector on the gauge (7).
Disconnect the charging line, but do not refit the Schrader valve cap at this stage.
Pressurizing the pedestal using the Vinten portable pump
To pressurize the pedestal using the Vinten portable pump, proceed as follows:
Remove the Schrader valve cap (16).
On the pump, fold down both the feet (P.3).
Push in the handle release button (P.5) and move the handle (P.1)to the horizontal position,
where it will lock.
Pull the hose (P.4) out of its stowage (P.2). Connect the hose to the pedestal charging valve
(16).
On the pedestal, push down on the weight tray (1) against residual pressure. At the safety
catches (3), push the rocker switches to the unlocked position.
Position the pump between the legs, standing with both feet on the fold-down feet (P.3).
WARNING! This pedestal must be pressurized only with clean, dry air or
nitrogen. A pressure reducing valve must be fitted to the pres-
sure line between the gas cylinder and the outlet connection of
the hose. The reducing valve must be screwed into the gas cyl-
inder outlet. The maximum pressure on the outlet side of the
reducing valve must not exceed 13.1 bar (190 psi). Do not pres-
surize the pedestal beyond the maximum safe working pres-
sure indicated by the leading edge of the red sector on the
gauge. The pedestal is fitted with a pressure relief valve as a
safeguard against over-pressurization. Do not attempt to adjust
the pressure relief valve.
WARNING! Do not pressurize the pedestal beyond the maximum safe
working pressure indicated by the leading edge of the red sec-
tor on the gauge. The pedestal is fitted with a pressure relief
valve as a safeguard against over-pressurization. Do not
attempt to adjust the pressure relief valve.

Balancing the load
After pressurization of the pedestal, the pan and tilt head and payload can be accurately balanced,
as follows:
Exercise the moving column (5) over its full travel at least twice, then position the column
in the mid-height position.
If the column tends to fall, remove a trim weight (2), (19) or increase pressure.
If the column tends to rise, reduce the pressure in steps of 0.15-0.20 bar (2-3 psi) using the
Schrader valve cap (16).
Refit the Schrader valve cap (16).
A correctly pressurized pedestal will balance its payload such that it can be moved to any
position over the full on-shot stroke of the moving column, with minimum effort, and it will
maintain its position when the steering ring is released.
Fine balance and temperature correction may be achieved by adding or removing trim
weights.
Using the Quattro-SL pedestal
Height adjustment
The column (5) has an on-shot stroke of 100 cm (39.4 in.) and the load can be moved over this
distance, in perfect balance, by raising and lowering the steering ring (4). The movement is ad-
justable for drag (17) and an on-shot clamp (6) can be used to hold the moving column in position
if fixed height operation is required. A markable height indication scale is provided on the second
stage of the column. Operators can use this scale to record working heights to be returned to
whilst shooting.
WARNING! A pressure retaining valve prevents pedestal pressure being
reduced below approximately 3.5 bar (50 psi).
WARNING! The Schrader valve cap (16) forms a primary pressure seal.
Always replace the cap and screw it down finger- tight.
WARNING! To ensure maximum stability, particularly when moving over
uneven surfaces, reduce pedestal height to a minimum.
Take care not to trap fingers under the steering hub or between
column elements while pedestal height is being reduced.

Drag control
Column movement is adjustable for drag and this is set according to operator preference by
means of the drag control (17) located at the base of the moving column. Turn the control clock-
wise to increase the drag setting, and counter- clockwise to decease it.
On-shot clamp
An on-shot clamp (6), located at the base of the moving column, can be used to hold the column
in position if fixed height operation is required. Move the clamp lever fully to the left to apply the
clamp. Move it fully to the right to release the clamp.
Steering
Directional control of the pedestal is achieved by turning the steering ring (4) mounted at the top
of the column. The steering system is geared so that the wheels turn by the same amount as the
steering ring. This ensures, for example, that with the pedestal set to crab, turning the steering
ring by 90° will also cause the pedestal to change direction by 90°. The steering ring is fitted with
indicators which, when aligned with the crab/steer pedal (15), indicate the straight-ahead position
and thus provide a reference point when steering.
Position indicators (12) in the centre of each vertical face of the base allow the camera operator
to accurately position the pedestal.
The pedestal has a crab/steer arrangement with a foot-operated changeover mechanism, which
provides a steer setting - one wheel steering, two fixed; or a crab setting - all three wheels turning
together. Pushing the pedal (15) operates the changeover mechanism which toggles the pedestal
between crab and steer.
Although the button can be pressed with the wheels in any position, the changeover will not occur
until the wheels are all facing forward, so the steering ring may have to be turned by up to 180°
before the changeover mechanism engages. This arrangement ensures that the fixed wheels will
always lock in the straight-ahead position when changing from crab to steer.
Steering rings of two diameters and with either type of steering indicator may be fitted (see Chang-
ing the steering ring).
Parking brake
A parking brake is provided on one wheel, operated by a red, foot-operated button (14), adjacent
to the crab/steer button.
To apply the brake, press down on the button. Press the button again to release the brake.
Cable clamps
Two cable clamps (13) are provided, mounted on the vertical faces of the base.
WARNING! This brake is intended for use only as a parking brake. Do not
apply the brake while the pedestal is in motion.
Back
17
Cable guard
An infinitely adjustable, continuous cable guard is provided in the skirt of the base, raised and low-
ered by means of a single knob (10). Height of the cable guard is displayed by a cable guard height
indicator (11) positioned below the adjustment knob.
Rotate the adjustment knob to set the cable guard to the required height.
The cable guard incorporates a spring-loaded mechanism to prevent damage if the pedestal is
pulled over an obstacle.
Transportation and storage
To prepare the pedestal for transportation and storage, proceed as follows:
Fully depress the moving column (5). Push down on the weight tray (1) and push the safety
catch rocker switches (3) to the locked position.
Using the Schrader valve cap (16), reduce pedestal pressure to 3.5 bar (50 psi).
Push down on the weight tray (1). At the safety catches (3), push the rocker switches to the
unlocked position. Allow the column to extend under hand restraint.
Apply the on-shot clamp (6).
Undo the four mounting bolts and remove the pan and tilt head.
To avoid the possibility of dust or abrasive particles collecting on moving components, re-
lease the on-shot clamp (6) and set the moving column (5) to minimum height. Push down
on the weight tray (1) and push the safety catch rocker switches (3) to the locked position.
WARNING! The Quattro-SL pedestal has a mass of 150 kg (331 lb). Take
care when lifting the pedestal. Do not lift the pedestal by the
steering ring - use the lifting apertures (9).
Local, national or international regulations may apply to the
transport and storage of pressurized pedestals.
NOTE: It is not necessary to reduce the pedestal pressure prior to transportation or
storage.
WARNING! A pressure retaining valve prevents pedestal pressure being
reduced below approximately 3.5 bar (50 psi).
WARNING! A pressurized pedestal will rise rapidly when the safety catches
are released. Do not lean over the pedestal when releasing the
safety catches. Always restrain the column by hand pressure
on the weight tray when the safety catches are released.

Servicing
General
The Quattro-SL pedestal is robustly made to high engineering standards and little attention is re-
quired to maintain serviceability save regular cleaning. Attention to the following points will ensure
a long and useful service life with minimum need for repair.
Routine maintenance
The Quattro-SL pedestal requires no routine maintenance other than regular cleaning.
During normal use, check the steering alignment, the effectiveness of the on-shot clamp and
check for radial or side play in the moving column.
If the steering is misaligned, re-align the wheels (see Wheel alignment).
Refer to the appropriate section in the Maintenance Manual if the on-shot clamp is ineffective, ex-
cessive radial or side play is apparent in the moving column, or any other defect is apparent.
Adjustments and repairs should be carried out only by a competent person.
Cleaning
During normal studio use, the only cleaning required should be a regular wipe over with a lint-free
cloth. Dirt accumulated during storage or periods of disuse may be removed with a semi-stiff
brush. Particular attention should be paid to the flats on the top stage of the column and to the
wheels, which are accessible for cleaning through the lifting apertures.
Use out-of-doors will require special attention, especially in adverse conditions. Salt spray must
be washed off with fresh water at the earliest opportunity. Do not allow water to enter the column.
Sand and dirt acts as an abrasive and should be removed with a semi-stiff brush or vacuum clean-
er.
Wheel alignment
Inaccuracies in the steering may be due to misalignment of the wheels, backlash in the steering
ring, or slackness in the steering belt or chains,
If misalignment of the wheels is suspected, carry out a tracking check, as follows:
Draw a straight line on the studio floor at least 4 m (13 feet) long.
Ensure that the pedestal is carrying a payload of approximately 80 kg (176 lb)
Set the pedestal to CRAB and carefully align the clutch wheels (under the crab/steer knob)
and one of the front wheels with the line on the studio floor.
NOTE: Do NOT use oil or grease on any exposed part of the column. This is
unnecessary and traps dirt which acts as an abrasive.
NOTE: Use only detergent-based cleaners. Do NOT use solvent- or oil-based cleaners,
abrasives or wire brushes to remove accumulations of dirt, as these damage the
protective surfaces.
Back
20
Push the pedestal 3.6 m (12 feet) along the line. The pedestal should not deviate more than
50 mm (2 in.) from the line.
Push the pedestal back to the starting point. The pedestal should not deviate more than
50 mm (2 in.) from the line.
Reposition the pedestal to align the wheels under the crab knob and the other front wheels
with the line on the studio floor and repeat the above check.
If the deviation exceeds the above limits, re-align the wheels as follows:
Remove any payload from the pedestal. Remove all trim weights from the weight tray and
